- Drawing appropriate structures or mechanisms is essential to answer the following.

a) Why shouldn't you use ethanol as a solvent for Grignard reactions?

b) Why don't we usually obtain a 100% racemization from an SN1 reaction?

c) Ethers have relatively lower boiling points compared to corresponding alcohols (same # of carbons). Why?

d) SN2 reactions need to be carried out in aprotic polar solvents. Why?

e) In Butan-2-one, show the most acidic and least acidic protons. Explain why.

f) Explain why addition of one mole of Br2 to buta-1,3-diene at high temperature gives 1,4-dibromobut-2-ene.

Please show all of your work. I will rate your answer. Thank you.
